After The Review

Decide The Next Action Before You Keep Reading Repository Material

Killer-Skills should not stop at opening repository instructions. It should help you decide whether to install this skill, when to cross-check against trusted collections, and when to move into workflow rollout.

Install Path

Start With Installation And Validation

If this skill is worth continuing with, the next step is to confirm the install command, CLI write path, and environment validation.
Trusted Recheck

Cross-Check Against Trusted Picks

If you are still comparing multiple skills or vendors, go back to the trusted collection before amplifying repository noise.
Workflow

Move To Workflow Collections For Team Rollout

When the goal shifts from a single skill to team workflows, approvals, and repeatable execution, move into workflow collections.

Workflow Routing (SYSTEM PROMPT)

Set up testing: "set up testing", "init testing", "bootstrap test infra" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/init-project.md -> EXECUTE: Copy templates, create specs/ dir, configure bunfig.toml

Define test scenarios: "write scenarios for X", "define test cases", "spec out the feature" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/write-scenarios.md -> EXECUTE: Create Given/When/Then specs from requirements

Run a TDD cycle: "run TDD on X", "red green refactor", "TDD this feature" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/tdd-cycle.md -> EXECUTE: RED→GREEN→VERIFY loop with 2-retry escalation

Run test pyramid: "run the pyramid", "run all test layers", "full test suite" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/run-pyramid.md -> EXECUTE: Static→Unit→Integration→E2E in sequence

Check for regressions: "backtest", "check regressions", "compare test results", "quality gate" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/backtest.md -> EXECUTE: Compare JUnit XML baselines, check coverage delta, enforce gates

E2E browser verification: "verify E2E", "browser test", "e2e scenarios", "smoke test the UI" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/e2e-verify.md -> EXECUTE: Run scenarios via devtools-mcp, auto-draft .spec.ts

Mutation testing: "run mutation tests", "check mutation score", "how good are my tests" -> READ: ${PAI_DIR}/skills/tdd-qa/workflows/mutation-check.md -> EXECUTE: Run StrykerJS, report mutation score (advisory)

Philosophy/patterns/mocking: Not in this skill — see CORE testing-guide.md, mocking-guidelines.md, interface-design.md.

Usage Modes

ModeFlow
New featurewrite-scenarios -> tdd-cycle -> backtest
Bug fixtriage-issue -> fix -> backtest
Confidencebacktest or run-pyramid
New projectinit-project (once)

Workflow steps are typed deterministic or agentic (Stripe Minions pattern). See references/blueprint-pattern.md.

Bombadil (v0.3.2) is experimental — invoke explicitly, not routed by default. → READ: workflows/explore-bombadil.md when user asks for Bombadil exploration.

Lifecycle Completion

Minimum Complete Cycle

  1. write-scenarios — Given/When/Then specs (mandatory human review gate at step 4)
  2. tdd-cycle — RED→GREEN→REFACTOR for each scenario
  3. backtest — regression check, baseline update

Complete when backtest passes with zero regressions and baseline updated.

Optional Extensions

ExtensionWhen to suggestPrerequisite
mutation-checkAfter backtest passes, for critical code pathsStrykerJS installed
e2e-verifyWhen feature has a browser UIdevtools-mcp available
run-pyramidBefore merging a PR, as final confidence checkTests exist at multiple layers

System-Level "Done"

A feature is fully tested when:

  • All quality gates pass (zero regressions, coverage not decreased)
  • Baseline updated
  • JM has reviewed and approved scenarios

Do not proactively run optional extensions unless JM asks or the feature touches critical code paths.

Composing Workflows

Canonical Sequences

Request typeSequenceSkippable steps
New featurewrite-scenarios → tdd-cycle → backtestwrite-scenarios skippable if JM provides inline requirements
Bug fixtdd-cycle (RED: failing test for bug) → backtestwrite-scenarios usually skipped for single bugs
Confidence checkbacktest or run-pyramidBoth standalone
Refactoringbacktest (before) → refactor → backtest (after)No TDD cycle — existing tests are the safety net

Ambiguous Requests

If a request spans multiple workflows, ask which workflow to start with rather than guessing. Example: "add auth and make sure nothing breaks" could mean write-scenarios + tdd-cycle + backtest, or just a confidence backtest on existing code.
